Santa Rosa Island Air Force Station (1952-1963) - A Cold War U.S. Air Force Radar Station established during the Korean War. Located on Santa Rosa Island in Santa Barbara County, California. Assigned a Permanent ID of P-15. Closed in 1963 and relocated to Lompoc Air Force Station, RP-15.

Construction

After negotiating a lease with the Vail Company, owners of the island, for 336.5 acres in four parcels, the Air Force hired civilian contractors Morrison Knudsen to construct the facilities. The facilities included a radar operation site, transmitting and receiving sites located at the top of Vail Peak and a cantonment area near the shore at Johnson’s Lee. Also included was a permanent pier to also be located at Johnson’s Lee. The Air Force paid an annual fee of $20,000 for the 15-year lease.

Radar Site Parcels
Parcel Acres Use Location Notes
A 155.0 Radar Operation Area Soledad Mountain and what would later be called Vail Peak
B 131.6 Radio Sites Two knolls on Navy Hill
C 30.0 Cantonment Area Johnsons Lee
D 60.0 Joint use For one mile east of the housing area

Construction work was essentially completed by the end of 1951 and a small detachment from the main squadron worked on the island readying it for occupancy by the full squadron.

Transportation support was supplied by the Navy, which provided water transport between Port Hueneme and the construction site. This support included a 78-foot PT boat that transported personnel to and from the island from Port Hueneme and Navy barges that supplied water and bulk cargo to the station.

Operation

The 669th Aircraft Control & Warning (AC&W) Squadron officially move in on 13 Feb 1952 and the site achieved Air Defense Net acceptance at 1100 hours on 16 Feb 1952. On activation, the site assumed the coverage of the Camp Cooke Lashup Radar Site (L-41) and Port Hueneme Lashup Radar Site (L-42) and they were subsequently closed. In 1952 the site was operating two FPS-10 radars. In 1955 a FPS-3 search radar was added to the site and in 1956 a GPS-3 backup search radar was added. A MPS-14 height-finder radar was added in 1958.

Note: Some sources indicate that operation was begun with a CPS-6B but Searching the Skies indicates that FPS-10s (CPS-6Bs with fewer components) were operating in 1952. FPS-10 components including the tower had CPS-6B nomenclature tags.

Closure

Santa Rosa Island AFS was deactivated on 31 Mar 1963 and the 669th AC&W Squadron move to Lompoc Air Force Station, RP-15. The Air Force then abandoned the facility, leaving all buildings, utilities, and much equipment to Vail & Vickers (owners of the island). At the time of abandonment by the Air Force, the site consisted of at least forty buildings and structures.

In the late 1980s, the Army Corps of Engineers removed asbestos and underground storage tanks, and the park service then burned most of the buildings. In the early 1990s, the National Park Service buried the remaining foundations and revegetated the terrain. Only one building remains on the Air Force sites, the motor pool building #147 remains.

Physical Plant

The physical plant of the site was divided into the main operations site, a cantonment area, and two radio sites. The main operations site housed the operations buildings, the radar towers, and the backup generators. The cantonment area housed the enlisted barracks, the bachelor officer's quarters, the orderly room, the dining hall, the motor pool and other support buildings. The site had no family housing area.

Two separate radio sites housed the radio equipment for directing aircraft intercepts.
